Brown Fused Alumina for Abrasive Tools
High-performance abrasive grain for bonded and coated tool manufacturing across metal, wood, and composite applications.
Why Use BFA in Abrasive Tool Manufacturing?
Brown fused alumina (BFA) is a key raw material in the production of industrial abrasives due to its high hardness, angular grain shape, and thermal stability. It is ideal for producing grinding wheels, sanding belts, flap discs, and other tools where cutting speed and wear resistance are essential.
- Mohs hardness of 9.0 ensures aggressive cutting action
- Thermal stability during high-speed grinding
- Available in a wide range of grit sizes and grain shapes
Typical Abrasive Tool Applications
- Bonded abrasives: grinding wheels, segments, sharpening stones
- Coated abrasives: sandpaper, sanding belts, fiber discs
- Non-woven abrasives and polishing pads
Suitable for metal, wood, ceramic, and composite material processing.
Recommended Grain Sizes
- Rough grinding tools: F12–F36
- General purpose sanding: F46–F80
- Fine polishing tools: F100–F240
Special-treated grains available for resin, vitrified, or electro-coated systems.
